Last weekend, at my home in the mid-atlantic region, we had an
incredible amount of rainfall after two months of drought. In the
past, we have had issues during heavy rain with the drain at the base
of the outside foundation stairway (areaway) clogging and the overflow
seeping in through the basement doorway.
During the night, I awoke to sound of the rain pounding on my roof and
thought I better head down and check the drain. The drain runs to the
sump pump in the unfinished area of the basement. I first checked the
sump and saw that no water was flowing in through the areaway drain
pipe or the a second pipe which runs from somewhere outside the
foundation. I went to the areaway drain and it was clogged. I
unclogged it and watched it drain. At that point I returned to the
sump and noticed water was pouring quickly from the foundation pipe
where none was before. At that same time, I realized I had water
leaking from a small crack in the foundation wall about five feet
above the floor. After draining for approximately 15 minutes the leak
slowed and eventually stopped. The water from the foundation drain
continued to run for another 45 minutes or so but that too eventually
stopped. Thankfully, I averted any major damages, though if we had
not been home or I had slept a bit more soundly it would have been
First, I have no explanation for why the foundation drain did not run
to the sump simply because the areaway drain was clogged. Is it
possible there was some sort of air lock created that prevented the
foundation from draining?
Second, There was a lot and I mean A LOT of water in the foundation.
The fact that we received such a large quantity of water on what is
now hard pan undoubtedly contributed to this, but should I be
concerned about this? Are there any ramification to having this much
water surrounding the foundation?
Third, the sump pump spews its contents to a pipe which is literally
an inch or two from the foundation wall. Is this appropriate? Should
the water be channelled farther from the house?
TIA for your responses,
